3.4. SELECTING THE WELDING PROCEDURE (2T/4T)

2T: MIG welding with double action of the start switch of the gun:

1. Switch closed - welding starts.

2. Switch open - welding ends.

4T: MIG welding with quadruple action of the start switch of the gun:

1. Switch closed - flow of shielding gas starts.

2. Switch open - welding starts.

3. Switch closed - welding ends.

4. Switch open - flow of shielding gas ends.

3.5. ADJUSTING WELDING DYNAMICS

The adjustment of MIG welding dynamics influences the properties 

of the welding arc and the amount of splatter. The recommended 

basic setting is ‘0’. The values -> min (-1...-9) provide a softer arc for 

diminishing the amount of spatter. The values -> max (1...9) provide a 

coarser arc, suitable when increased arc stability is desired and when 

using 100% CO²

 shielding gas for welding steel. 

3.6. THERMOSTAT

The temperature control of the machine prevents the power source from 

over-heating.This means that the machine can not become damaged if loading 

exceeds  the  specified  load  factor  during  welding. When  the  signal  lamp 

indicating overheating is lit, the welding circuit can not be activated. The 

lamp will turn off after a pause of about three minutes, and welding can be 

started again in the usual way by pressing gun switch.

3.7. WIRE FEED SWITCH

The wire feed switch will start the wire feed motor without opening the gas valve. The power 

source will start up, but without providing welding power.
